For the pocket, I've just made another little "quilt" that is put together where you layer the batting, then two pieces of fabric right sides together and sew around the edges leaving an opening for turning. Turn it and sew it on 3 sides, in the middle of one side of your quilt. The opening of the pocket should point towards the center of the quilt. You can then fold up the quilt behind the pocket and then fold the pocket over the quilt to get your quillow.
I know it's difficult to "see" something like this in words, but hopefully it will help.
